The delay in Convex rewards has caused a drop in Curve APY, since Convex rewards have now caught up to the same level as Curve rewards. This means that Curve users have seen a decrease in the rewards they receive, as Convex rewards have taken over the higher rewards. This has resulted in a decrease in rewards for Curve users, and an increase in rewards for Convex users. Ultimately, this means that Convex has killed most of the rewards that Curve users were receiving.
